auto save and recovery

[Neil Best]

I am trying to understand why Aquamacs' behavior seems to be different  
than that of emacs on Linux that I am used to with respect to auto-
save and recovery of open files.  Last night my Mac locked up and I  
had to do a hard reboot.  When I go to M-x recover-this-file on  
something that was open when the system went down and had some unsaved  
changes I get "Auto-save file /var/folders/3u/3uyC1V0LEBahCJn84YT3tE++
+TI/-Tmp-/#!Users!nbest!org!gtd.org# not current" and the named file  
does not contain any of the recent changes that I expected to be able  
to recover.  The default settings in the "Auto Save" group look  
reasonable except for the random-looking destination folder under /var  
-- I am used to the #filename# files appearing in the same directory  
as the original files on Linux.  How could the auto-save file not be  
current?  This seems like a bug to me but maybe I am missing  
something.  Any advice?  I lost some important notes in this  
episode.  :(

Neil,
the path is correct, since it would be bad behavior to leave extra  
files in the same directory (which do not get hidden on the Mac).
However, I'm not sure why it isn't "current", or what this means - the  
machinery for this is exactly the same as on GNU/Linux.  Auto-saves  
are made in more or less regular intervals - could it be that the file  
is simply a few minutes too old?

- David

I haven't been able to figure that out.  Aquamacs refuses to load the  
auto-save file and when I inspect its contents I don't see the changes  
since my last save.  My first hypothesis was that these files don't  
survive a system reboot, but I was thinking of them as if they were  
in /tmp.  Now I look at an auto-save file when I don't need it and  
recent chancges appear there as expected, but when I need the feature  
to work it fails.  Am I they only one experiencing this?  Thanks for  
taking a look.

What was the nature of your shut-down?
Do you have journaling enabled for the boot volume (see Disk Utility)?
